In physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time in the future, until distances between particles will infinitely increase.

The end of the world or end times [2] is predicted by several world religions (both Abrahamic and non-Abrahamic), which teach that negative world events will reach a climax. Belief that the end of the world is imminent is known as apocalypticism , and over time has been held both by members of mainstream religions and by doomsday cults .
Each year for the past 78 years, the Bulletin of the Atomic Scientists has published a new Doomsday Clock, suggesting just how close – or far – humanity is to destroying itself.
The universe could then consist of an infinite sequence of finite universes, with each finite universe ending with a Big Crunch that is also the Big Bang of the next universe. A problem with the cyclic universe is that it does not reconcile with the second law of thermodynamics , as entropy would build up from oscillation to oscillation and ...
The Big Crunch is a hypothetical scenario for the ultimate fate of the universe, in which the expansion of the universe eventually reverses and the universe recollapses, ultimately causing the cosmic scale factor to reach absolute zero, an event potentially followed by a reformation of the universe starting with another Big Bang.
This theory could explain the mysterious disappearance of information about matter and energy inside a black hole, but it the concept has its flaws.
The universe will become extremely dark after the last stars burn out. Even so, there can still be occasional light in the universe. One of the ways the universe can be illuminated is if two carbon–oxygen white dwarfs with a combined mass of more than the Chandrasekhar limit of about 1.4 solar masses happen
